Circuit structure for implementing remote control signal emission instruction control in microprocessor

Abstract

The invention relates to a circuit structure for implementing remote control signal emission instruction control in a microprocessor, wherein the circuit structure comprises a program counter module, a stack register, an instruction pointer register, a multiplexer, a program memory, an instruction register, a storage register, an accumulator, an arithmetic logic unit, a state register, a data memory, a connection register, and a data bus. Because only the data memory is connected to the instruction register by the data bus, when remote control instruction control is performed by the circuit structure, except the operation on the data memory, addressing modes of other instructions are direct addressing modes, the operation can be completed in one period, and the instruction operation time is shortened. Simultaneously, all instructions are 8 bits, thereby simplifying design of hardware and reducing difficulty and complexity for programming personnel. And an instruction pipeline manner, overlaps instruction execution and instruction fetch processes, and raises the instruction execution efficiency. The circuit structure of the invention has advantages of simple structure, low cost and wide application range.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to the technical field of remote control transmitting processor circuits, and specifically refers to a circuit structure in a microprocessor for realizing remote control signal transmitting instruction control. Background technique [0002] In recent years, infrared remote control technology has been rapidly developed and widely used in the field of electronics, especially in the field of home appliances, such as color TVs, DVDs, and air conditioners. With the improvement of people's living standards, the pursuit of products is more convenient to use and more intelligent. With the higher requirements for the number of buttons supported by the remote control, the development time of the whole machine, the cost of the whole machine, and power consumption indicators, etc., The requirements in instruction design also become the focus of consideration. [0003] For the infrared remote...

AI Technical Summary

Problems solved by technology

[0004] Traditional general-purpose microprocessor instructions are too large and complex, and there are many types of instructions. Many instructions are often not used when using a specific function, which greatly increases the burden and redundancy of the system.

The instructions of some microprocessors are too simple. Although there are few types of instructions and the structure is very simple, in many cases when using a specific function, two or three instructions, or even more instructions, are needed to complete. Execute command takes longer

It greatly reduces the working efficiency of the microprocessor, which not only consumes the storage space of the system, but also increases the power consumption of the entire system.
